Nuclear fuel cycle costs in
dollars per year ($/yr), and in mills per kilowatt-hour (mills/
kwhr) are computed and tabulated for each region of a multiregion
reactor core, on the basis of AEC-leased nuclear fuel material and
of privately-owned nuclear fuel material. Fuel cycle costs are
computed separately for each region or zone, for core designs of
any configuration or combination of material depletion or enriched
uranium fuel or other special nuclear material. Printed output of
the program includes (a) detailed fuel cycle costs for each zone
in tabular form, for AEC-leased and privately-owned nuclear fuel
material, respectively, (b) a summary tabulation of nuclear fuel
costs for all regions of the complete core, including fixed
charges on working capital required for core fabrication and for
nuclear fuel material, (c) a summary tabulation of certain
computed performance and economic data, viz., average residence
time, annual fuel throughput, unit electrical energy yield, annual
power generation, and core fabrication costs, and (d) a tabulation
of all input data for all regions. The printing of data described
in (a) and (d) above is optional with program use.

Certain of the operating and
economic parameters will generally remain constant for a wide
range of reactor core designs. Therefore, the program includes a
set of standard values for these parameters so that the amount of
basic input data required is minimal. The use of these so-called
standard values is optional with the program user, and any
combination of or all of these standard values may be modified as
desired. Fuel processing costs may be computed for spent-fuel
management programs which provide for the reprocessing, separately
or in any combination, of single or multiple spent-fuel batches
from one or more regions having the same or different final
enrichments. Thus, the lowest cost spent-fuel management program
can be readily determined.
